not heard of those issues, their have been some recent issues with both NVIDIA and AMD card not switching. You should consult the MADVR forum to find out which is the best driver version and make sure you are on the latest version.

Also update LAV filters, the version this comes with are out of date now, you need update these in the install folder.

 I'll give that a try as currently I've not done any manual updates to the filters, just using what comes with Kodi 

 The process of updating LAV Filters is described in the link in my signature.
